Excellent app ! Finally one that works all by itself

I tried a number of sleep apps that I very quickly abandoned. It kind of defeats the purpose of a sleep app that you have to tell: “I’m asleep now.” This app figures it out all alone!

The metrics returned from Sleep Watch are also more relevant and much easier to understand than other similar apps. The straightforward approach, in a clear simple language makes this app “editor’s choice”!

There is only one slight (very small) reason why I only gave four and three-quarter stars: timing! The app waits until I’ve just started my work day to ask “how did you sleep”. Given the fact that the Apple Watch has figured out that I’m awake and moving, I would prefer to get the question immediately (within 5 to 10 minutes of continuous movement) on the watch and not an hour later on my phone. Personally, once I’ve picked up my phone, my work day has started. I am already in the middle of reviewing, planning, calling etc when Sleep Watch wakes up and pops the question that I just push away.

I would also like to see a different wording in the “discover” section. Instead of asking “how did you sleep on 21st June”, I would prefer “today” or “yesterday”. It just makes things clearer and keeps you from having to look back in the calendar and see when the 21st was.

Keep up the excellent work!

No-touch sleep-tracker, great potential!

I have used apps like Sleep Pulse and Sleep++ and other paid sleep trackers for the Apple Watch and I can happily say this is my favourite one. It has correctly detected 19/20 sleep records without even having to tell my Watch when I'm sleeping. Almost zero interaction with my Watch so as long as you wear your watch while sleeping, you'll always get your sleep recorded!

I suggest that they add manual sleep tracking (for afternoon naps etc) and also to change the bar for the sleep quality (maybe change to similar to Jawbone bat graph?). Also maybe tie up with a company that does "coaching" on how to improve sleep (like read your steps or active calories that day and relate it to your sleep etc). Basically, something to help you aim to improve your sleep rather than just tracking it.

I would highly suggest this app to anyone who owns an Apple Watch and wants to track their sleep. This is the only app you'll need.

UPDATE review :

I forgot that I had an amazing feature with my old sleep tracker (Jawbone UP24) which did a silent vibrate alarm which only wakes you up when you're in light sleep phase around 15-30 minutes before your proposed alarm - and I wake up like a Disney princess I tell you hahaha!

Good, but...

This could be a great sleep tracking app, except for a few serious problems. First, privacy. Sleep is an incredibly personal thing, and the company hasn’t clearly told us where and how our data is being stored, or who’s got access to it except for mentioning “third parties” in their privacy policy. I assume it’s not too bad, since it’s a medical company and an Apple app, but they could do more to reassure us. Also, useless functions. I’m not sure what an account does, besides putting an email address with the data and making it even less private, because iCloud saves our sleep data. The Discover tab does nothing but crash the app. Finally, despite several emails, I’ve never received any replies, support is apparently nonexistent.
